HeatShield Flue Liner Replacement Nationwide

HeatShield Flue Liner Replacement: The Puyallup Owner’s Guide

We stock and install HeatShield-compatible flue liner replacement in Puyallup, with typical installed pricing between $2,400 and $4,800 depending on flue height, diameter, and whether the existing liner is ceramic or stainless. Most HeatShield liner jobs in the South Hill corridor and downtown Puyallup area are completed in a single day, and we carry common diameters on our trucks. Homeowners usually discover the problem when a Level 2 inspection turns up spalling, gaps, or delamination in the ceramic coating, or when they smell smoke in the house during a burn.

Which HeatShield Models This Applies To

HeatShield manufactures two distinct liner systems, and knowing which one is in your flue determines replacement strategy. The Cerfractory Flue Seal is a spray-applied ceramic coating used to resurface clay tile liners; it is not a standalone liner but a restoration layer that bonds to existing tile. The HeatShield Cerfractory Sleeve is a standalone stainless steel liner with a ceramic bonded interior, rated for higher continuous temperatures. We see both in Puyallup homes, particularly in the 1980s and 1990s builds near Meridian where wood-burning inserts were common.

To identify your system, look for a metal tag at the top of the flue collar or check your original installation paperwork. The Cerfractory Flue Seal application date and batch number should be recorded there. If the tag is missing, we measure liner diameter with a caliper and run a camera to determine wall construction. Ceramic coating typically measures 3/8 to 1/2 inch added to the original tile ID; a Cerfractory Sleeve runs true to stainless dimensions (5.5-inch, 6-inch, 7-inch, or 8-inch ID are standard in this market).

We source replacement materials through Haven’s buying network from HeatShield, DuraFlex, and Gelco. For Cerfractory Flue Seal failures, we sometimes recommend a full stainless replacement over re-coating, particularly if the underlying clay tile is cracked or the flue has offset joints. For Cerfractory Sleeve failures, we match diameter and gauge to maintain UL 1777 listing. Level Two Chimney Puyallup is an independent service provider with no affiliation to HeatShield.

Signs Your HeatShield Flue Liner Replacement Is Failing

• Smoke odor in living spaces during operation. This means combustion gases are escaping through gaps in the liner wall, usually at a failed seam or spalled ceramic section. In Puyallup’s wet winters, freeze-thaw cycles accelerate ceramic delamination where moisture has entered the flue.
• Visible flaking or powder at the cleanout door. Cerfractory coating degrades into a sandy residue when its silicate binder breaks down. We see this often in homes burning unseasoned Douglas fir, which is abundant locally and burns wetter than owners realize.
• Draft problems that worsen on windy days. A compromised liner loses the smooth interior surface that establishes proper draft. South Hill homes on the bluff catch more wind, and a degraded liner can’t maintain consistent negative pressure.
• Discolored or hot exterior masonry. Heat transfer through a thinning or gapped liner section can raise the temperature of surrounding brick. This is the condition that leads to pyrolysis of adjacent framing over time.
• Failed inspection with camera evidence of gaps exceeding 1/2 inch. NFPA 211 considers any gap or crack that allows combustion gases to reach combustible materials an immediate hazard. We document this with photo records under Haven Standard Clause 4.

Replacement Cost & What’s Included

What drives the range: flue height from firebox to crown, diameter, whether the existing liner must be extracted or can be left in place, and crown repair requirements. Every quote is written before work starts, with parts specified by brand and gauge, labor itemized, and warranty terms stated. We include a camera-scan inspection and documented photo record on every job, standard under Haven Standard Clause 4 since 2009. Materials come through Haven’s buying network from HeatShield, DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield.

DIY or Call Us?

There’s a safe middle ground here, and then there’s where DIY ends. You can verify your liner diameter with a tape measure at the top of the flue, check for visible gaps with a flashlight from below, and confirm your model tag exists. What you cannot safely do is enter the flue, work on a ladder at roof height with stainless steel sections, or attempt to remove a failed liner without proper extraction tools. The risk is real: a falling liner section, a ladder slip on a Puyallup winter morning, or an incomplete installation that vents carbon monoxide into wall cavities.

Camera goes in first. Price gets written down second. Work starts third. That’s how Corrine Halstead runs every job, and it’s been the practice at Level Two Chimney Puyallup since 2009. Call (253) 323-5667 and we’ll schedule a camera inspection with a written quote. No charge for the estimate, and we offer a free second opinion on any competitor’s written quote you bring us.
